Really stop lying to yourself. Android is a powerful mobile OS that can be adapted to many situations.

You should tell that to my wife who has an Android phone and finds that it doesn't really even seem to be well adapted to phone-related situations. She's constantly having problems with it, particularly with freeze-ups and crashing.

I think it's more truthful to phrase your sentence like this. "Android is a powerful mobile OS that can be shoehorned into many situations but can do none of them very well."

The problem with text entry boxes in (so far as I can tell) every single browser out today, is that they are fixed width. I can have a nice big 30" monitor and want to be able to type a paragraph about this size in a single friggin' line of text across the whole monitor (more common is trying to convey source code in a text window; wrapping really sucks for source code). But, I can't, because the text box is default sized so that it fits without scrolling on my mother in law's 10-year-old 15" CRT set at 640x480. So, it's a little postage-stamp square on my 30" cinema.

Unfortunately this is more of an issue with the designers, and not the technology. It's quite easy to make a textarea that resizes with your site design (unless the site is fixed with... but any site that heavily relies on user input generally is not.. and should not be). takes a few width: 100%'s, and you're good to go.

Now of course, that only deals with horizontal scaling. But hey, try making a post here, and click on those up and down arrows in the top right of the input area.
